^-^ Meet the yellow alien girl, with yellow skin, white hair, a yellow sweater, and some shorts. Now, the overlay on her mouth may look weird to you, but Planet Minecraft makes it farther away from the actual face than it ism so in game you don't even notice the overlay on the mouth ^u^
I did use a skin base, so here's the link to that:

Also, the hair and sweater were not originally mine, I just edited them, so here are the originals:
Hair:

Sweater:

I changed the coloring and shape of both of the above, and I added a face to the sweater.
